Many of us have a basic (and probably old) battery charger such as this that can do the job, but modern chargers with sophisticated charging sequences can do a far better job of charging a battery while also ensuring any ill effects are minimized to prolong battery life. Additionally, slow charging (10 amps or less) is the preferred method to replenish the energy in a battery. Higher current rates charge the battery faster but can cause the battery to heat and shed the paste material on the plates more quickly, and can shorten the service life of the battery.
